Composite insulators are usually made of glass or ceramics. Due to their small size, light weight, strong shock resistance, and high pollution resistance, they have become the darling of electric power work.
Due to frequent exposure to the outdoors, high-voltage wires are often exposed to harsh weather conditions such as fog, rain, dew, snow, and melting ice, that is, under these harsh conditions, a large number of casualties due to electrical leakage occur, which has become a popular phenomenon among people. However, it is different with composite insulators. Composite insulators are usually made of glass or ceramics, and ceramics and glass are organic composite materials. The biggest advantage of organic composite materials is that their hydrophobicity can make the surface of composite insulators. Water is separated to form independent water droplets. Without the connection of sewage, there is no electrical conductivity, thus solving the problem of current leakage or local strong current.
1. The umbrella tray made of high molecular polymer with silicone rubber as the matrix has the advantages of good hydrophobicity, corrosion resistance and aging resistance. It can effectively prevent the occurrence of pollution flashover accidents, reduce manual cleaning, and avoid zero-value maintenance, which provides a reliable guarantee for the safe operation of transmission lines.
2. The core rod is made of glass fiber reinforced resin rod, which has high tensile strength (>1100Mpa), which is about 1.5 to 2 times that of ordinary steel, and 3 to 5 times that of high-strength porcelain. In addition, the mandrel also has good vibration damping, creep resistance and fatigue fracture resistance.
3. The connection between the hardware and the mandrel adopts a non-damaged mechanical crimping connection, which is the most advanced connection method in the world today. The advantages are: the connection is safe and reliable, the crimping stress is evenly distributed, the integrity of the glass fiber bundle of the mandrel is not damaged, and the excellent characteristics of high tensile strength can be fully exerted.
